At first I thought there was a bootleg early release of the movie Ant Man in Thailand, but I soon realized this was clearly way too short.

In the city of Rayong in Thailand, a young man wanted to imitate Jackass and launched the challenge to resist the stinging red ant bites. On the road, the young man undresses and keeps only his underpants. One of his friends then rub a branch, freshly cut and on which there is a nest of red ants...

Well, you can guess the rest, or you can watch.
